Constructor & Destructor Documentation

CSdpSearchRequester(RSdpSession &, CSdpAgentEng &)

CSdpSearchRequester	(	RSdpSession &	aSdpSession,
		CSdpAgentEng &	aParent
	)	[private]

Constructor: Adds this CSdpAttributeRequester to Active Scheduler. Sets parent, and passes client side object for session with SDP server (currently ESock). Sets up cont state member to default 0 length descriptor.

Parameters

RSdpSession & aSdpSession
CSdpAgentEng & aParent

Member Functions Documentation

ConstructL()

void

ConstructL

(

)

[private]

Currently does nothing.

DoCancel()

void

DoCancel

(

)

[private, virtual]

Cancels current asynchronous requests. This could be with the Sdp server (currently ESOCK) or if this CSdpRequesterBase is in idle state it cancels the time out timer (set-up to perform a disconnection after a defined length of time).

HandleSearchResponseL()

void

HandleSearchResponseL

(

)

[private]

IssueRequestL()

void

IssueRequestL

(

)

[private, virtual]

Requester is now connected. Called down from requester base class. Time to actually issue the request

NewL(RSdpSession &, CSdpAgentEng &)

CSdpSearchRequester *	NewL	(	RSdpSession &	aSdpSession,
			CSdpAgentEng &	aParent
		)	[static]

Standard NewL method. Note: need to pass the client side object of the SDP service session, and the CSdpA.gentEng parent which is managing this CSdpAttributeRequester active object.

Parameters

RSdpSession & aSdpSession
CSdpAgentEng & aParent

RequestCompleteL()

void

RequestCompleteL

(

)

[private, virtual]

Response parameter format is

         Total service record count		TUint16
		Current service record count	TUint16
		Service Record Handles			unadorned list of TUint32's
		Continuation State				1 + 0-16 bytes

Reset()

void

Reset

(

)

[private, virtual]

Called when base requester idle timer expires, and when an error is reported Cleans up and makes sure we really are disconnected.

RunError(TInt)

TInt

RunError

(

TInt

aError

)

[private, virtual]

Called automatically when a RunL leaves. Calls appropriate error handling function in the CSdpAgentEng parent.

Parameters

TInt aError

SearchRequestL(const TBTDevAddr &, CSdpSearchPattern &, TUint16, const TDesC8 &)

void	SearchRequestL	(	const TBTDevAddr &	aRemoteDev,
			CSdpSearchPattern &	aUUIDFilter,
			TUint16	aMaxCount,
			const TDesC8 &	aContState
		)

Sets up appropriate member variables, then attempts to connect to remote device. (If connection is made the state machine takes over to make the actual search request.)

Parameters

const TBTDevAddr & aRemoteDev
CSdpSearchPattern & aUUIDFilter
TUint16 aMaxCount
const TDesC8 & aContState

SendSearchRequest()

void
